Abstract

A steering angular velocity computing device has a steering angle detector (16), a timer (20), and a steering angular velocity computing unit (17). The steering angle detector (16) detects a change in a steering angle, the timer (20) measures a required time from a time at the steering angle changed until a time at the steering angle next changed, and the steering angular velocity computing unit (17) computes, after the detector has detected a change in the steering angle, the steering angular velocity by dividing an amount of change in the steering angle by the required time corresponding to the amount of change and outputs it. When the steering angular velocity is being reduced, the steering angular velocity computing unit (17) outputs the steering angular velocity during a first extended output period longer than the required period. With this structure, the steering angular velocity is outputted with a good accuracy when the steering angular velocity is being reduced.
